According to Nogales, Sonora municipal police, officers responded at 10:20 p.m. on Friday to a report of a dead body at Boleiro TD’s on Calle Elias. When they arrived, they met with paramedics from the Cruz Roja who told them that they had found the victim, a 64-year-old resident of Nogales, Ariz., in a private room, showing no vital signs.

The man, who had a pacemaker, apparently died of a heart attack.

The paramedics also told police that they had seen one of the club’s employees, 36-year-old Raul Pelayo Huerta, take a gold chain from the body.

Pelayo, who works as a DJ at the club, allegedly confessed to taking the chain and returned it to police, saying he had removed it only in order to apply first aid...

The three employees, along with Loremy Martinez Ceballos, a 29-year-old dancer at the club, were taken into custody and placed at the disposition of a local prosecutor “for the clarification of responsibilities,” the police department said in a news release.
